发明名称 Signal recording and/or reproducing apparatus
摘要 A signal recording and/or reproducing apparatus can record and/or reproduce a character information, which could not be sufficiently demodulated conventionally, together with a video signal, by deriving a program information signal S9 from a character signal S8 transmitted as multiplexed with the video signal S1, outputting it to a control circuit 12, coding or decoding only character information S5 corresponding to a program information selected by a user at a clock lower than a broadcasting signal, re-inserting it into the video signal S4 and recording and/or reproducing the combined signals.
